SwiftUI make AVCaptureVideoPreviewLayer play nice with xStacks - swiftui

Question

I have a barcode scanner that is using Vision, and it works great. How do I get the camera to play nicely with my VStack? Currently when I add the cameraView, the cameraView doesn't play nicely with the VStack, meaning it gets added as AVCaptureVideoPreviewLayer frame that I have to use to display the camera.
How can I make this work with the VStack so it's easier modified?
struct BarcodeScannerView: View {
var pitchDegrees: CGFloat
var cameraView = CameraView()
var body: some View {
VStack(spacing: 20) {
Rectangle()
.frame(width: 40, height: 5)
.cornerRadius(3)
Text("Barcode Scanner")
.multilineTextAlignment(.center)
.font(.body)
Spacer()
cameraView
Spacer()
Button(action: {
print("Scan")
}, label: {
Text("Scan")
})
.frame(width: 200, height: 44)
.background(Color.black)
.foregroundColor(Color.white)
.clipShape(Rectangle())
}//VStack
.frame(maxWidth: .infinity)
.frame(height: 300)
.padding()
.background(Color("Warm White"))
.clipShape(Rectangle())
.shadow(radius: 5)
.padding(.all, 5.0)
}//body
}
CameraView

func setupPreview() {
previewLayer = AVCaptureVideoPreviewLayer(session: captureSession)
previewLayer.videoGravity = .resizeAspectFill
previewLayer.connection?.videoOrientation = .portrait
previewLayer.frame = CGRect(x: 0, y: 0, width: view.frame.width - 30, height: 200)
previewLayer.cornerRadius = 15.0
previewLayer.borderWidth = 1
previewLayer.borderColor = #colorLiteral(red: 0, green: 0, blue: 0, alpha: 1)
previewLayer.shadowRadius = 5.0
view.layer.addSublayer(previewLayer)
